Hydrocarbon A (C₈H₁₂) upon treatment with H₂/Pd is converted to hydrocarbon B (C₈H₁₄).  On treatment with cold, dilute and basic KMnO₄, A is converted to C (C₈H₁₄O₂).  When heated with KMnO₄, in basic solution, followed by acidification, either A or C produces the meso form of 1, 4-cyclohexanedicarboxylic acid.
